HongHao 4inch 2G4R Gym Timer LED Interval Timer Training Time and Rest Time Alternate CountdownCount up As A Stopwatch

Easy instructions- use it every day at my home Box

The 4" display is AWESOME - you can probably see the digits from space - however the volume is so low you won't hear it unless you're within just a few feet and it's not adjustable. If you have a small space and don't have a lot of other sounds to distract this is a good buy but if you use it like I did in a large room with competing sounds (radio, heavy bags, voices, etc) you're going to be disappointed with the volume.

Dont buy!

What a waste of time. Doesn't come with a battery and when I got a battery, the remote didn't even work. Returning now.

Just as advertised. Easy to operate

Very good
